Microsoft debuts Scout agent, homegrown reasoning model - Axios

At its Build developer conference on June 2, 2026, Microsoft announced its first internally developed reasoning model, MAI-Thinking-1, and a personal AI agent named Scout. Scout is designed to integrate with Outlook and Teams to help users prepare for meetings.

Microsoft's entry, MAI-Thinking-1, is intended for complex reasoning tasks, though the company did not release specific performance figures at Build. Scout's functionality is limited to productivity tasks within Microsoft's ecosystem, focusing on meeting preparation.

Build is Microsoft's annual developer conference where the company typically unveils new tools and platform updates. The debut of MAI-Thinking-1 and Scout indicates Microsoft's strategy to develop proprietary AI models and agents, reducing dependence on external partners. The products are expected to be integrated into Microsoft's existing productivity suite.
